ANTON BECKER, OF COLUMBUS, OHIO, ASSIGNOR TO THE RALSTON STEEL CAR COMPANY,

OF COLUMBUS, OHIO.

UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Nov; 26, 1907.

Application tiled March 18. 1907. Serial No. 362.956.

To all whom it may concern: y

Be it known that I, ANTON BECKER, a resi- -dent of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Under frames for Cars; and I do hereby declare the following to be a full, clea-r, and exact description of the invention, such as will enable others skilled-in -the art to which it apper- .ing the bolster iaphragms in place.

A further object is to stren then the corner construction of the under rame.

With these objects in view, the invention consists in certain novel features of construction and combinations and arrangements of arts as hereinafter set forth and pointed out 1n the claims.

In the accompanying drawings: Figure l is a perspective view of a portion of an underframe embodying my improvements; Fig. 2 is a detail sectional View; Fig. '3 is a detail view of the corner construction; Fig. 4 is a fragmentary side elevation.

1 re resents the central girder of a car underrame, and 2 the bolster located transversely on the center girder, the end sill 3 of the underframebeing secured at the forward ends of draft sills (not shown) secured to the center irder. The side sills 4 are sup )orted upon t e bolster, and at their forwart ends, said side sills are secured upon the end sill, the end sill being thus disposed below the plane of the side sills, as clearly shown in myv patent above referred to. Sub-sidesills 6 are dis osed to depend from the side sills, at the en s thereof and are secured thereto and to the end sills. In the angles formed by the sub-sills and the end sills, triangular brackets 7 are secured for the purpose of strengthening the corners of the framework, and these corners are further strengtlwiwd' by angle irons 8 which may be secured, not only to the side sills, sub-sills, and end sill, but also to the superstructure.

The bolster 2 comprises two channel irons 9, 9 spaced a short distance apart and at the ends of the bolster, stakes 10 are located. These stakes are made of angle or channel irons (being U-shapcd in cross section) and are disposed between the channel-iron members 9 of the bolster, said stakes extending to the plane of the bottoms of said channel-iron members, and securely bolted to the webs of the latter. A cover late 11 is disposed upon the bolster and is o a length to extend beyond the end stakes 10, said cover plate bcmg recessed atits ends for the accommodation of said stakes. l'pon the projecting ends 12 of the cover plate, the side sills 1 are mounted and may be secured thereto. The side sills are thus disposed against the outer faces of the stakes 10 and are bolted thereto.

To the inner face of each member 9 of the bolster, a diaphragm 13 is securely bolted. This diaphragm is provided at its lower and inner edges with a laterally rojecting flange 14, the'vcrtical portion of 'w iich is bolted to the vertical wall of the center sill, and said flange being bolted, at the juncture of its vertical and inclined portions, to an angle iron 15 secured at the base of the center sill. It will, of course, be understood that two diaphragms such as above described, ill be provided for each bolster member and that they are located at res ective sides of the center girder or sill. strap 16 extends under the center girder, and is secured at its respective ends to the inclined flanges of the dia hragms.

S ight ichanges might be made in the details of construction of my invention without departing from the s irit thereof or limiting its scope and hence I do not wish to limit myself to the precise details herein set forth.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a car under-frame, the combination with the bolster'members, of'stakes secured between said members and side sills supported upon the bolster members outside of said stakes and secured thereto.

2. In a car underframe, the combination with the bolster members, of stakes secured between said bolster members, each of said stakes consisting of a channel iron having its flanges projecting inwardly, and side sills lo- 52 s'imoaa cated upon the bolster members outside said stakes and secured to the body of said stakebetween the inwardly projectingfianges I r of the latter.

In a car underfra-me, the combination with the bolster members, of stakes secured between said members, a cover plate mounted upon said bolst er members and extending beyond the stakes, and side sills mounted of 3 upon the ends of said cover plate and secured 10 to the stakes. v

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
